Johnny Wong and Wallapak Tavanapong Receive a Grow Iowa Values Fund Grant to Develop Software for Computer-Aided Quality Control for Colonoscopy

06 Jul, 2007

Colonoscopy is an endoscopic technique that allows a physician to inspect
the inside of the human colon to screen for colorectal cancer---the second
leading cause of cancer deaths in the US. Millions of colonoscopic
procedures are performed annually. However, an objective method that
estimates the quality of colonoscopy (e.g., how much effort was undertaken
to insure maximal inspection of the visible parts of the inside of the
colon) does not exist, but is of significant importance. Together with
collaborators at Mayo Clinic Rochester and University of North Texas (UNT),
Drs. Wong and Tavanapong have pioneered methods and software tools for
automatically measuring objective quality of colonoscopy. To the best of
their knowledge, the invention is the first of its kind in the world. This
research work also received the 2006 ACG (American College of
Gastroenterology) Governors Award for Excellence in Clinical Research for
"the Best Scientific Paper".
The goals outlined in this Grow Iowa Values Fund (GIVF) proposal are: 1) To
improve the automated objective quality measurement algorithms and software;
2) To evaluate the effectiveness of the invention at several hospitals and
clinics. The proposed tasks will help EndoMetric, an Iowa-based startup
company, to commercialize the endoscopic research results.
Broad Impact: The technology will enable large-scale, objective quality
control in day-to-day procedure-based medical practice, which is currently
not feasible. Therefore, the technology is attractive for all hospitals and
out-patient clinics that strive to optimize healthcare delivery.
